[0002] With the development of industry, the amount of steel used is increasing. In the process of using steel casting molds, there will be residues on the surface of the mold after the workpiece is processed. In order to avoid affecting the next processing of the steel casting mold, it is necessary to use processing equipment to clean the surface of the steel casting mold. The cleaning of the processing equipment can effectively reduce the residue on the surface of the steel casting mold. However, the existing steel casting mold surface treatment equipment still has certain use defects during use, such as:

[0003] The utility model announcement number CN114425537A discloses a large casting mold surface cleaning device, which uses a high-pressure air pump, a nozzle, a motor and a screw.
